     [ https://issues.apache.org/jira/browse/HDFS-3501?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Aaron T. Myers updated HDFS-3501:
---------------------------------

    Description: The StandbyCheckpointer and 2NN currently do the right thing in renewing their krb5 creds before attempting to perform a checkpoint to the active NN, but the active NN makes no attempt to renew its own krb5 creds before connecting to the standby NN or 2NN to fetch the new merged fsimage file.  (was: The StandbyCheckpointer currently does the right thing in renewing its krb5 creds before attempting to perform a checkpoint to the active NN, but the active NN makes no attempt to renew its own krb5 creds before connecting to the standby NN to fetch the new merged fsimage file.)
        Summary: Checkpointing with security enabled will stop working after ticket lifetime expires  (was: Checkpointing with security + HA enabled will stop working after ticket lifetime expires)
